Introduction : Paroxysmal supraventricular tachycardia (SVT) can be very bothersome and may potentially lead to considerable health-care utilization. Non-parenteral medication is currently unavailable for the rapid termination of paroxysmal SVT. However, an intranasal spray formulation of etripamil, a short-acting calcium-channel blocker, is under investigation as a convenient, safe, and rapidly efficacious means to terminate paroxysmal SVT. Areas covered : This review summarizes the clinical rationale, potential benefit, and clinical trials safety and efficacy data for the use of etripamil nasal spray to terminate paroxysmal SVT...

INTRODUCTION: Ventriculoatrial (VA) conduction is a critical component in many arrhythmias, has a diagnostic value in electrophysiology study (EPS), and is implicated in pacemaker-mediated arrhythmias. This study sought to characterize retrograde conduction during EPS and to utilize it as a diagnostic tool in patients without AV block. METHODS AND RESULTS: Patients with intact AV conduction undergoing EPS were included in this study to systematically evaluate baseline VA conduction...

Superficial venous thrombosis (SVT) or superficial thrombophlebitis is characterized by thrombi within superficial veins, with partial involvement or occlusion of the lumen and inflammatory reaction along the course of the vein. Clinical diagnosis tends to be straightforward, but supplementary tests and examinations are needed to confirm thrombosis extension and possible thromboembolic complications. SVT can be associated with deep venous thrombosis in 6 to 40% of cases, with asymptomatic pulmonary embolism (PE) in 20 to 33%, and with symptomatic PE in 2 to 13%...

PURPOSE: Electrophysiological studies and ablation procedures expose both physicians and patients to a significant amount of radiation. Most 3-D mapping systems provide improved tracking of catheters and enable radiation exposure to be reduced or even eliminated. However, there are no data on the ability of the Rhythmia ™ mapping system (Boston Scientific) to minimize fluoroscopy time and dose. METHODS: Here, we report on the feasibility and safety of a novel non-fluoroscopic approach (NFA) that uses the Rhythmia ™ mapping system and a novel navigation-enabled ablation catheter in SVT and atrial flutter procedures, and describe in detail our modified procedural work-flow...

The new guidelines for the management of supraventricular tachycardia (SVT) were published by the European Society of Cardiology (ESC) in September 2019. The key message of the guidelines is that catheter ablation should be offered as a first line treatment to most patients during a comprehensive discussion of the risks and advantages. This recommendation recognizes that catheter ablation has nowadays become a widely established, effective and safe treatment method with a very low complication rate, which has revolutionized the treatment of SVT due to the substantial technical developments in recent years...

Myeloproliferative Neoplasms (MPN) course can be complicated by thrombosis involving unusual sites as the splanchnic veins (SVT). Their management is challenging, given their composite vascular risk. We performed a retrospective, cohort study in the framework of the International Working Group for MPN Research and Treatment (IWG-MRT), and AIRC-Gruppo Italiano Malattie Mieloproliferative (AGIMM). A total of 518 MPN-SVT cases were collected and compared with 1628 unselected, control MPN population, matched for disease subtype...

Supraventricular tachycardias (SVT) are common, with atrioventricular nodal reentry tachycardias (AVNRT) being the most common paroxysmal supraventricular tachycardia. The pathophysiological understanding and the catheter ablation of SVTs have developed steadily in recent years. For example, dividing AVNRT into "typical" and "atypical" depending on the HA-, VA-interval and AH/HA ratio is recommended. Because of higher rates of recurrences after cryoablation, radiofrequency ablation has prevailed in AVNRT...

Sustained fetal supraventricular tachycardia (SVT) complicated by hydrops fetalis carries a significant risk of morbidity and mortality. While there is no clear consensus on first- and second-line therapy options for the management of fetal SVT with or without hydrops fetalis, there exists significant nonrandomized experience with a number of antiarrhythmic agents that has founded the basis for management. Furthermore, recently published meta-analyses and ongoing multicenter prospective studies have aimed to bridge the gap in the literature...

Splanchnic vein thrombosis (SVT) including portal, mesenteric, splenic vein thrombosis and the Budd-Chiari syndrome, is a manifestation of unusual site venous thromboembolism. SVT presents with a lower incidence than deep vein thrombosis of the lower limbs and pulmonary embolism, with portal vein thrombosis and Budd-Chiari syndrome being respectively the most and the least common presentations of SVT. SVT is classified as provoked if secondary to a local or systemic risk factor, or unprovoked if the causative trigger cannot be identified...
